Electric Actuator/Slider Type Belt Drive AC Servo Specification/Series LEFB Model Selection Selection Procedure Check the work load-speed. Check the cycle time. Check the allowable moment. Selection Example- 1 Mounting orientation: Horizontal upward Workpiece mounting condition: Check the work load-speed. <Speed-Work load graph> (Page 3) Select the target model based on the workpiece mass and speed with reference to the <Speed-Work load graph>. Selection example) The LEFB40S4S-2000 is temporarily selected based on the graph shown on the right side. Check the cycle time. Calculate the cycle...
